Stretch fabric panels under the arms provide freedom of movement, while padded ears on the hood offer extra protection against the cold. Tailored in a slim, shaped fit with reverse darts to enhance the silhouette, the liner features elastic binding at the hem and cuffs, invisible zip side pockets, and inside-out construction.
